dz数据库使用的亚马孙rds，经常提示数据库负载高怎么解决

Toools

DELETE FROM `pre_common_session` WHERE `sid` = ? OR `lastactivity` < ? OR ( `uid` = ? AND `ip1` = ? AND `ip2` = ? AND `ip3` = ? AND `ip4` = ? AND `lastactivity` > ? )

DELETE FROM pre_common_session WHERE sid='P1ra5l' OR lastactivity<1675084612 OR (uid='0' AND ip1='17' AND ip2='241' AND ip3='227' AND ip4='42' AND lastactivity>1675085752)

能帮忙看下这个吗，这个数据库运行时候，波动高的（卡顿的）时候运行的sql语句。。这些 pre_common_session都是啥啊占了这么多
